The first forecast model run in each cycle is the 12km Eta.
This model generates an 84 hour forecast at 00Z and 12Z and a 48 hour forecast
at 06Z and 18Z over the the U.S. as soon as possible for early guidance
to the NWS and the meteorological community at large. Forecast hour output
is generated every 3 or 6 hours depending on the type of grid.

Jobs eta_dump_00/06/12/18 are run at 00Z, 06Z, 12Z and 18Z, respectively.
These jobs dump additional ADPUPA data at 0111Z, 0654Z, 1313Z, and 1850Z
for ingesting into the Eta forecast model run at 00Z, 06Z, 12Z and 18Z,
respectively. If no ADPUPA data is available, this job will fail
and the Senior Duty Meteorologist (SDM) must
determine the cause for non-receipt of data, notify the appropriate
person/group to resolve the problem, notify users of the delay in
generation of Eta model forecast and products, and coordinate the
rerun of the Eta dump job after the data relay problem has been
resolved.

Jobs eta00/06/12/18_dump_alert are run at 00Z, 06Z, 12Z and 18Z,
respectively. These jobs are released by the appropriate Eta data dump
(eta_dump_xx (xx being 00, 06, 12 or 18)) job when the Eta observational
data counts are critically low (close to no data for lower than the
30 day average for any data type (buoy, metar, etc.).

Jobs eta_dump_post_00/06/12/18 are run at 00Z, 06Z, 12Z and 18Z, respectively.
These jobs list contents of the BUFR data dump files and if necessary,
converts BUFR data dump files to various other formats (i.e.,ieee).

Jobs 220_00/06/12/18 are run at 00Z, 06Z, 12Z and 18Z, respectively. These
jobs preprocess the BUFR data; performs cyclone bogus processing; and performs
quality control of the BUFR data for ingesting into the Eta forecast model.
Each job requires 12 nodes, 1 task per node.

Family 230_00/06/12/18 are run at 00Z, 06Z, 12Z and 18Z, respectively.

Jobs 230_00/06/12/18_main prepares model boundary fields for use by their
respective Eta forecast model. This job is released
upon the completion of BOTH the appropriate Eta model dump job
(eta_dump_xx) and Early Data Assimilation System (EDAS) job 284_xx
(xx being 00, 06, 12 or 18).

Jobs 230_00/06/12/18_mkbnd creates the Eta boundary conditions from the
global model. Each job requires 3 nodes, 11 tasks (2 nodes
using all 4 processors and 1 node using 3 processors). This job is
released when an event flag (release_mkbnd) is set by the appropriate
230_xx_main job (xx being 00, 06, 12 or 18).

Jobs 235_00/06/12/18 are run at 00Z, 06Z, 12Z and 18Z, respectively. These
jobs perform a regional 3-d variational analysis on pressure coordinates.
The horizontal analysis grid is every other row of the eta h-grid. The
analysis increments are interpolated in the horizontal as necessary to
get to the staggered points left out of the analysis grid. Then vertical
interpolation to the Eta coordinate is done before the increment is added
to the Eta guess. Each job requires 28 nodes, 110 processors (27 nodes
using all 4 processors and 1 node using 2 processors).

Jobs 235_00/06/12/18_quilt are run at 00Z, 06Z, 12Z and 18Z,
respectively. These jobs read in small Eta restart files written by
each processor and creates a single global restart file. This job
is released upon the completion of the appropriate 3-d variational
analysis job 235_xx (xx being 00, 06, 12 or 18).
